Specification of Letters Patent.

Patented Feb. 2a, 1914.

Application filed June 24, 1912. Serial No. 705,609.

To all whom it may concern:

Be it known that I, JOHN S. HEDDEN, a citizen of the United States,residing at Newark, in 'the county of Wayne and State of New York, haveinvented a new and useful Egg-Tray, of which the following is aspecification.

This invention relates to a collapsible carton.

The principal objects of the invention are to provide an improved formof collapsible box and to shape the blank from which the box is formedin such manner as to effect a marked economy in material, at the sametime preventing any waste or scrap mate rial, by arranging for theformation of a number of blanks from a single strip or web of material,all of the material being used.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made with in the scopeof what is claimed without departing from the spirit of the invention.

In the accompanying drawing, forming part of this specification,-

Figure 1 is a plan View of an elongated strip or web of paper or othermaterial, the ends of the strip being torn away, the strip showing onewhole blank and the end portions of the two adjoining blanks; Fig. 2 isa perspective view of one of the blanks, after it has been cut andpartly folded into the form of a box; Fig. 3 is a similar view showingpart of a box after it has been completely formed and then collapsed;Fig. l is a perspective view showing a complete carton in expandedcondition; Fig. 5 is a similar view showing the carton collapsed.

The blanks for forming the boxes of the present invention preferably arecut or stamped in any suitable manner from an elongated web or strip ofpaper as indicated in Fig. 1, in which one whole blank is indicated atthe center and the end portions of two other blanks on opposite sidesthereof.

In forming the blanks, the web or paper is cut on the full lines in Fig.1 and then folded on the dotted lines.

Referring to the complete blank in Fig. 1, the reference numeral 1indicates the bottom of the box which is defined by the dotted foldlines 2 2 and 3-4. Connected with the ends of the bottom 1 are bottomflaps or ends 5-5, the rear corners of which are cut away on the curvedlines 66.

The back or one side of the box is indicated by the numeral 7, and isdefined in the blank by the dotted lines 3-8 and 9-9. The back 7 isformed at the ends thereof with back flaps l0-10 which are arrangedpreferably as indicated in 1, that is to say, the back flaps 10preferably are drawn out into pointed ends. By an examination of Fig. 1,it will be seen that the cut away portions between each back flap 10 andeach bottom flap 5 is of the same shape as the back flap 10, and informing a plurality of blanks the back flap 10 of the left hand blank,shown in Fig. 1, is cut out of the space between the back flap 10 andthe bot tom flap of the middle blank. Similarly, the back flap 10 of theright hand blank in Fig. 1 is cut out of the space between the back flap10 and the bottom flap 5 of the middle blank. The reference numeral 11indicates the top of the box which is defined by the dotted line 8, line12, and side lines 13-18. The top flap is indicated by the numeral 14-,and as shown best in Figs. 3 and 1, this top flap 1 1 is adapted to betucked down inside the front of the box. The ends of the front flap 14,as indicated in Fig. 1, preferably are cut away at the corners, asindicated at 1515. The front or other side of the box is indicated bythe with diagonally extending crease lines 20-2O adjacent the endsthereof, and each of the back flaps 101O of the complete blank, shown inFig. 1, and back flaps 10 and 10 of the two adjoining blanks, shown in Fig. 1, is formed with a crease line 21.

It will be observed that the three blanks shown in Fig. 1, are cut outof an elongated strip of material without wasting any of the paper andthat consequently there is a marked economy in material.

In forming a box or carton according to the present invention, acomplete blank, such as shown in Fig. 1, is employed. The bottom fiaps 5are folded upward on the dotted lines 22; the front 16 is folded upwardon the dotted line a; and the front flaps 1818 are folded rearward onthe dotted line 17, so as to overlap the bottom flaps 5 on either theinner or outer sides thereof, whichever is desired. The back 7 is foldedupward on the dotted line 3; the back flaps 10-10 are folded forward,preferably on the outer sides of the bottom flaps 5 and the front flaps18. The portions or tabs 10' of said back flaps 10, that is, theportions outside of the crease lines 21, are then riveted or otherwisesecured to either the adjacent bottom fiap 5 or front flap 18, or toboth, as indicated by the staples 23, in Fig. i. The top 11 is folded onthe dotted line 8 and the top flap 1% is folded on the dotted line 12,thereby producing the complete box, as shown clearly in Fig. a.

After the complete box has been formed, said box is collapsed asindicated in Figs. 3 and 5, by folding the front 16 backward anddownward, on the crease lines 2020, and then folding the ends of the boxinward on the crease lines 21.

It will be observed that the crease lines 21 constitute the sole creaselines at the ends of the box, and that the bot-tom flaps 5 and frontfiaps 18 are not formed with crease lines, these flaps folding snuglyagainst the bottom of the box without the use of crease lines.

In using the carton as an egg box, the partitions shown in Fig. 4 areinserted therein.

Particular attention is directed to Fig. 4, wherein it will be notedthat the uncreased fiaps or ends 5 are provided with portions extendingbeyond the fold lines 21 of the fiaps 10, so that these projectingportions may swing flatly against the flaps 10 when the ends or fiaps 5are unfolded, to limit the outward movement of the flaps 5. This is ofimportance, in connection with the cut away portions 6, which permit theends of flaps 5 to fold without creasing. Thus, the ends or flaps 5 andthe flaps 10 are provided with cotiperating uncreased portions adaptedto swing flatly together when the carton is unfolded, to preventexcessive movement of the ends or flaps 5. lVhen the partitions areplaced within the carton, it will be obvious that the sides and ends ofthe carton will be locked against inward movement, the ends beingprevented from bulging or moving outwardly excessively, due to thecontacting portions above described.

Particular attention is also directed to the fact that those corners ofthe cut away flaps 1O adjoining the ends 5 are cut on ogee or compoundcurves, or may be said to be out on reversely extending lines, inasmuchas the lines on which the said corners are cut, may be reversed so as toextend in precisely the same direction. The term reversely extendinglines is thus conveniently employed for describing that line on whichthe corners of the flaps 10 are cut, adjoining the ends 5, whereby thecut away flaps of adjoining blanks will interfit, as clearly seen inFig. 1. It will also be noted that the other corners of the flaps 10, orthose corners remote from the ends 5, and the cut away corners of theends are cut on reverse lines, whereby with the peculiar cut of thecorners of the flaps adjoining the ends 5, the openings between the endsand flaps 10 will be precisely of the same contour as the flaps 1Othemselves.

What is claimed is:

l. A collapsible carton blank comprising a bottom having sides and ends,the sides having flaps attachable to the ends, one side having a topprovided with a flap, the corners of the flaps of that side having thetop being cut away, and the adjoining corners of the ends being cutaway, those corners of the cut away flaps adjoining the ends being outon reversely extending lines, and the other corners of the said flapsand the cut away corners of the ends being cut on reverse lines, inorder that the opening between the ends and the cut away flaps will beprecisely of the formof the cut away flaps.

2. A collapsible carton blank comprising a bottom having foldable sidesand ends, one side having a foldable top and foldable flaps to cooperatewith the ends, said flaps having diagonal fold lines forming tabsattachable to the ends, the other side having foldable flaps attachableto the ends, the adjoining corner portions of the first mentioned flapsand ends and the other corner portions of the first mentioned flapsbeing cut away, those corners of the cut away flaps adjoining the endsbeing cut on reversely extending lines, and the other corners of thesaid flaps and the cut away corners of the ends being cut on reverselines, in order that the openings between the first mentioned flaps andends will be the same as those of the first mentioned flaps, the endshaving portions to project beyond the fold lines of the first mentionedflaps when the In testimony that I claim the foregoing as tabs areattached to the ends to swing my own, I have hereto affixed my signatureagainst the first mentioned flaps when the in the presence of twoWitnesses.
